INMETRO certification

INMETRO certification is issued by an OCP (Organismo de Certificação de Produto) accredited by Cgcre, INMETRO's accreditation arm, and never by INMETRO itself. The general rules sit in Portaria INMETRO 200/2021, and the portaria for your product family decides whether certification is compulsory, which ABNT standard applies, which certification model is used, and how often the factory is audited. Two facts surprise most foreign manufacturers. The certificate is held by a Brazilian company with a CNPJ, and under the most common model the OCP audits the plant wherever it is.

Is INMETRO certification compulsory for my product?

Only if a portaria says so. Compulsory certification covers the product families with a published portaria: toys under Portaria INMETRO 563/2016, household electrical appliances under Portaria INMETRO 371/2009, both as amended, and a long list from automotive components to medical devices. Outside those families certification is voluntary and a commercial decision. Each portaria is its own rulebook. Two families that look adjacent can follow different models, different standards and different audit cycles, with costs that bear no resemblance to each other.

Searching for "how to get INMETRO certification" as if it were one process is the first wrong turn. The right first question is which portaria names your product, because that document also fixes how long the whole project takes.

Which certification model will the portaria assign?

Portaria INMETRO 200/2021, the general product certification requirements (RGCP), defines the models, and each product portaria picks one. Modelo 5 is the standard for series production: type testing in a laboratory, an initial audit of the factory's quality system, then surveillance with samples pulled from the market or the plant and a periodic re-audit. Modelo 7 certifies a lot: the OCP samples and tests that consignment, and the certificate dies with it. Other models cover type testing without a factory audit and appear in fewer portarias.

The model is the INMETRO certification cost driver. Modelo 5 means an auditor at your plant, wherever it is, with travel billed to you, and a re-audit at the interval the portaria sets. Modelo 7 means no audit and no maintenance, but a fresh certificate for every shipment, which only pays for a one-off consignment.

What does the OCP do, and how do I choose one?

An Organismo de Certificação de Produto is a private body accredited by Cgcre for a defined scope. It reviews the documents, sets the test plan against the standard in the portaria, sends samples to a laboratory accredited by Cgcre, audits the factory, issues the certificate and registers the product with INMETRO.

Accreditation is per scope. An OCP accredited for household appliances cannot necessarily certify toys, and switching bodies means starting the file again. Ask for the accreditation scope in writing before you sign. Ask, too, whether the OCP has audited outside Brazil before; the portaria does not care, but your schedule will.

Who holds the certificate?

A Brazilian company with a CNPJ. A foreign manufacturer cannot be the holder, so most projects route it through the importer. That works, and it ties the certificate to that importer: it is not transferable, so changing distributor means certifying again. A representative appointed for the purpose keeps the certificate independent of the commercial relationship.

After issue, the OCP registers the product with INMETRO, and the registration number is the reference a buyer, a retailer or a customs broker checks. A certificate without a current registration is a piece of paper.

Why is the factory audit the surprise?

Modelo 5 assesses the plant's quality system as well as the sample. For a manufacturer outside Brazil that means an auditor flying in, and that line item is missing from almost every first estimate. A maintained ISO 9001 system covers most of what the auditor asks about: incoming inspection, final testing, calibration, records.

Maintenance is the other half. The certificate requires follow-up audits and retesting at the intervals the portaria sets, so the three-year cost is often larger than the first-year cost.

Who does what

The audit happens at the manufacturing plant. For a factory outside Brazil that means auditor travel, and it is the line item missing from almost every first estimate.
